Είναι η Αθήνα ασφαλής; Αλήθεια τώρα, υπάρχουν κίνδυνοι στην Ελλάδα για έναν ξένο;
Ναι, πολλά μπορούν να συμβούν, αν δεν προσέχεις.
Και εγώ ξένος πήγα στην Αθήνα από την Πάτρα. Η Πάτρα είναι μία μικρή πόλη, σχεδόν χωριό.
Η Αθήνα είναι μητρόπολη.
Δηλαδή η μισή Ελλάδα μένει στην Αθήνα. 
Άρα η Αθήνα (λογικό είναι ότι) είναι επικίνδυνη.
Αλλά ποτέ δεν έπαθα τίποτε κακό.
Ένας είναι ο κανόνας που μου είπε ο παππούς μου για την Αθήνα και τον άκουσα καλά.
"Στην Αθήνα χρειάζεσαι τρία πράγματα: Πόδι, μάτι και αυτί."

Is Athens safe? Honestly, are there dangers in Greece for a stranger?
Yes, a lot can happen, if you don't pay attention.
I myself came to Athens as a stranger from Patras. Patras is a small city, almost a village.
Athens is a metropolis.
Which means that half the population of Greece resides in Athens.
Therefore (it makes sense that) Athens is dangerous.
But never anything bad happened to me.
The rule that my grandpa told me about Athens is one and I listened carefully:
"In Athens you need three things: legs, eyes and ears".

 But honestly, nothing ever happened to me?
Well, ok. Once something did happen.
I got robbed of my camera. But?
I was not using neither of the three. Neither my leg, nor my eyes or my ears whatsoever.
I was tasked by a newspaper to write an article on a flea market that takes place every Sunday,
near Monastiraki. If you take a walk down Ermou street, after Thission,
on Sunday morning a union of homeless ρακοσυλλέκτες (trash pickers) sells everything they have collected
during the week. But, they are collectors, right? And we are on Ermou street, right?
And good old Hermes apart from a Messenger God and a Merchant,
was also the patron of the thieves. Remember that Homeric Hymn?

Enough said, Hermes is also a thief. But this robbery was absolutely my fault!
I was thirlled with the merchandise. I was taken away and not paying any attention.
Instead of doing the interview with the homeless guy, taking my photos and writing the article,
I fantasized about that time that the trash pikcers had found a real manuscript of Cavafy.
And, well, spent a good two hours looking for Cavafy, eyes and ears shut down.
When I decided it was time to do the interview, the camera was lost.

But for a stranger and a foreigner there are, indeed, other dangers.
Because it is easier to get carried away. Here are some examples. Also here  and here.
Again, though,  the rule "Πόδι μάτι και αυτί" works on these examples.
Say, someone in New York, out on the street, offered to buy you a coffee.
You don't know the person. He/She might look attractive. Would you grab the coffee?
Probably not, so why not act the same in Athens and Greece?
It also always depends on the context. If the person is an eighty year old yaya (grandma)
sitting on her porch and making the coffee, why not talk to her?

In any case, this post is on Emergency Situation (Κατάσταση Εκτάκτου Ανάγκης)
and hopefully this phrasebook will help you through, in a Greece that is safe anyway.

And after the Ten Plagues of Egypt and the Calamities of the Pharaoh, a little ditty song that might appear useful:

Είμαι σε κατάσταση εκτάκτου ανάγκης                           I am in an emergency situation
μέσα σε μια φάση τραγική                                              in a phase that is tragic
Είμαι σε κατάσταση εκτάκτου ανάγκης                           I am in an emergency situation
και η σωτηρία μου είσαι εσύ                                           And my salvation is you
